1. 打开新的窗口并传送参数: :KP'xf.

接收参数: o-=d|dWG
string a = Request.QueryString("id"); FNm6/_u3
string b = Request.QueryString("id1"); XVDd1#h

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") px}7If

3.删除表格选定记录 hY=

int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; JM-ce8U
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ?)[zLnxc&

8.关于日期格式 c*x J=Gz6d
QKp+;$SE'
日期格式设定 +cz"`T`X 2
DataFormatString="{0:yyyy-MM-dd}" 7tpAZ<{
r5MxjuOB1
我觉得应该在itembound事件中 E-UB -"6
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) xm<v"><
l |08
9.获取错误信息并到指定页面 :y+B;qw
6=ZRn gQ
不要使用Response.Redirect,而应该使用Server.Transfer Q`.'-iq
xwTijSj
e.g `z9)YH
// in global.asax 2d-TU_JqX
protected void Application_Error(Object sender, EventArgs e) { T@;! yz}Pf
if (Server.GetLastError() is HttpUnhandledException) Gw
~{V
Server.Transfer("MyErrorPage.aspx"); Qg'c?[~W@
|d,F-9iw
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ==%`e/~Y
} .S~@BI(|<
L;/9L[s,
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 LP.HS'M~u

10.清空Cookie h5L=M^z!>
Cookie.Expires=[DateTime]; !]$V9F{K
Response.Cookies("UserName").Expires = 0 WGH%92
